Only bases attained from hits count toward this total. Total bases can be calculated from commonly used baseball statistics by using the formula TB = 1B + 2 x 2B + 3 x 3B + 4 x HR. Singles (1B) can be represented as 1B = H - 2B - 3B - HR which, when combined with the given TB formula, allows for the reduced formula found at the top of the page.
